Distribution of bacterial rDNA sequences in catheter samples.

1Numbers designate the percentage of clones in a catheter library that were classified in a phylotype. High values for each specimen are in bold. 2Designates whether a patient was subjected to systemic antibiotics during catheterization. 3Identified by Blast search of database culled of environmental clones. 4Mean BLAST percent identity scores of query sequences to top BLAST hit. 5Total number of sequences. 6Low abundance clones were removed from table because of space limitations. See Table S1.
